yes it will lower your hormones on a severe cal. cut, amoung other problem's. Go for a 500 calorie reduction per day. That will put you at around a 1 lb. loss per week and get you to were you want to go. Starving yourself is not the proper way to lose weight.
You will lose a few lbs. this way but then your body will shutdown. Your body will think it's starving and will start slowing everything down. Not what you want.
